System and method for capturing 3D face

Abstract

A system and method are disclosed, wherein the system for capturing 3D face includes following elements: (1) a digital image system, for acquiring a photo; (2) a 3D graphic processor, for manipulating image data of the photo, rendering the image data to a 3D graph or storing the image data and the 3D graph; and (3) a display device, for displaying the image data or the 3D graph; the method is characterized by manipulating image data by a 3D graphic processor, and obtaining better quality without using a powerful CPU.

1 . A system for capturing 3D face, applicable to a portable hand-help device, comprising: 
 a digital image system, for acquiring a photo;    a 3D graphic processor, for manipulating image data of the photo, rendering the image data to a 3D graph or storing the image data and the 3D graph; and    a display device, for displaying the image data or the 3D graph.    
   
   
       2 . The system for capturing 3D face as recited in  claim 1 , further comprising a storage device for storing the photo, the image data and the 3D graph.  
   
   
       3 . The system for capturing 3D face as recited in  claim 1 , further comprising a central processing unit for coordinating the system.  
   
   
       4 . The system for capturing 3D face as recited in  claim 1 , wherein the 3D graphic processor is used for displacing, rotating, and zooming the photo.  
   
   
       5 . The system for capturing 3D face as recited in  claim 1 , wherein the portable hand-help device is Digital Still Camera (DSC), Digital Video (DV), Personal Digital Assistant (PDA), mobile electronic device, 3G mobile phone, cellular phone or smart phone.  
   
   
       6 . A method for capturing 3D face, applicable to a portable hand-help device, comprising the steps of: 
 selecting a 3D face model for a living object;    deciding a number of acquiring angles of the 3D face model;    loading and displaying a rough outline of the 3D face model on a display;    pointing a camera of the hand-held device to the living object;    moving the camera of the hand-held device to place a face of the living object within the rough outline;    taking and saving a photo of the face when the face is placed within the rough outline;    loading the photo of a first acquiring angle;    displaying the photo of the first acquiring angle with a detailed 3D face model outline;    performing an interactive displacement, rotation or zoom to match the photo to the detailed 3D face model outline;    cropping and saving the photo within the detailed 3D face model outline as a texture of the first angle when matching the detailed 3D face model outline; and    mapping the texture to the 3D face model.    
   
   
       7 . The method for capturing 3D face as recited in  claim 6 , wherein if the decided acquiring angle(s) is multiple, the method repeats the step of loading and displaying the rough outline of the 3D face model and the following steps before the step of loading the photo of the first acquiring angle.  
   
   
       8 . The method for capturing 3D face as recited in  claim 6 , wherein if more photos need to be manipulated, the method repeats the step of loading an added photo and the following steps before the step of mapping the texture to the 3D face model.  
   
   
       9 . The method for capturing 3D face as recited in  claim 6 , wherein the detailed 3D face model outline is corresponding to key features of the face including eyes, nose and mouth.  
   
   
       10 . The method for capturing 3D face as recited in  claim 6 , wherein the portable hand-help device is Digital Still Camera (DSC), Digital Video (DV), Personal Digital Assistant (PDA), mobile electronic device, 3G mobile phone, cellular phone or smart phone.
